Answer: A
Step-by-step explanation:
Answer:
11.45mm^2
Step-by-step explanation:
Given data
Circumference= 12mm
The expression for the circumference is
C= 2πr
12= 2*3.14*r
12= 6.28r
r= 12/6.28
r= 1.91mm
Hence the area of each small circle is
A= πr^2
A= 3.14*1.91^2
A= 3.14*3.6481
A=11.45mm^2
Answer:a.100+(hx25)
b.120+(hx20)
c.4 hours
h=hours
Step-by-step explanation:
116 + 38 = 78
